By using examples of the rotor system which rotates about two axes with section or without section, we build the vectorial method of the kinetic parameters analysis of the rotors with many axes. The vectors connected for the pole and the axis are used for the analysis of kinetic parameters, by the use of which the rotation properties of the mass configurations are interpreted introducing the mass moment vectors for the pole and the axis, as well as the kinematic vectors rotators. Expressions for the corresponding linear momentum and angular momentum, as well as their derivatives in time are derived. By these expressions vectorial equations of the rotor system dynamics are derived, as well as the expression for the kinetic pressures on the rotor system bearings.
